So I’ve been running into this problem a lot. Sometimes I have a need to copy/paste posing info from one rig to an updated version of that rig with some small changes. When I copy/paste special or use the pose copier, the info pastes into the new rig, but some of the deformers always seem to be wrong. Ex:The arm should have a bend to it made by the deformer, but when pasted the arm ends up just being completely straight with no deformer info…
What I end up having to do is copy/paste the deformer group into the new rig and that will usually fix it… but this is ends up being a lot of work if you have multiple deformers breaking and/or multiple poses to work on. Any advice or solutions would be greatly appreciated.
